Bluescreens related to CPU overheating?

Specs: Windows 10, Intel i7 4770k, 32GB 1600MHz RAM
I've recently been bothered by my computer bluescreening while playing some more than usually demanding video games. Usually it says SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (dxgmms2.sys), but recently I've been getting a lot of different ones, like
WHEA_UNCORRECTABLE_ERROR, IRQL_NOT_LESS_OR_EQUAL and DRIVER_IRQL_NOT_LESS_OR_EQUAL (e22w7x64.sys).

As the bluescreens occur, my avg. CPU temperature is all the way up to 85-95C, peaking at around 95-100C.
Processor is an Intel i7 4770k running at stock speeds, using the stock cooler.

Would getting a new cooler help solve these problems, or does it look like something else might be the culprit?

High temperatures can cause all sorts of issues. You need to solve those before you investigate other areas. The first step is to ensure the computer is not full of dust, particularly the CPU heatsink. Another possibility is that the CPU needs reseating with thermal compound applied according to the CPU manufacturers instructions. Better cooling would be the next step.

Always pop back and let us know the outcome - thanks

Your stock heat sink should have come with preapplied thermal compound which should be OK as long as you carefully installed it ONCE only and did not need to move it around or remove it AND you cleaned off the top of the CPU from any oils from your skin during installation with rubbing alcohol AND the lock down clips are fully locked into the motherboard. I definitely recommend removing the heat sink, cleaning off all of the old thermal compound and reinstalling it with a decent quality compound. Here is a link for the instructions that will apply to nearly any thermal compound that you end up purchasing. Find your CPU here and read the proper application method:

I have the i5 4690K at stock speeds and use this heat sink (though I paid less when I purchased it) and my typical temp non-gaming is 28C to 30C:

It should not be needed but if you continue to have trouble or plan to eventually OC it, you might consider it or something similar. What ever you chose, make sure that it will fit into your case.

You have to be a little bit crazy to keep you from going insane.

From what I could find, dxgmms2.sys has to do with NVIDIA graphics drivers; e22w7x64.sys has to do with Killer e2200 PCI-E Gigabit Ethernet Controller drivers. If that's what you have, I suggest you uninstall the drivers & then reinstall the latest available.

As for the CPU temp, assuming your temp readings are accurate, the heatsink/fan should be removed from the CPU & the thermal material replaced as per the instructions posted by Fingers.

I'll do a driver reinstall and apply some new thermal compound, I'll be back with the results.
